Don't stuff your pockets with noisy, rattling pellet tins. Instead, load up several 10-rd mags so you're ready to go at a moment's notice. The Air Arms S510 air rifle is a superior hunting rifle, so you know you're going to do a lot of hunting with it. Might as well stock up on some mags and spend more time shooting and less time fumbling with tins in the field.

Things I would have changed: The inner barrel needs to be made from a stronger metal. As other people have noted, the .25 cal version of this leaves the outer edge very thin and after a short time the metal breaks rendering the magazine useless. Being able to order a replacement inner barrel for much less than the $50 for a mag would be a reasonable compromise by AA.

What others should know: Be prepared to only get a little over 6 months of occasional use from these in .25
